R Commands

This chapter describes the Cisco NX-OS virtual port channel (vPC) commands that begin with R.

reload restore

To configure the time to restore the virtual port channel (vPC) peer links, use the reload restore command. To revert to the default delay value, use the no form of this command.

reload restore [ delay delay_value ]

no reload restore

 
Syntax Description

delay

(Optional) Specifies the time to wait before assuming that the vPC peer is dead and to restore the vPC links.

delay_value

Time (in seconds) for restoring the vPC links. The range is from 240 to 3600, and the default is 240.

 
Command Default

240 seconds

 
Command Modes

vPC domain configuration mode

 
Command History

Release
Modifications

6.0(2)N1(1)

This command was introduced.

Examples

This example shows how to enable the reload-restore interval for 240 seconds (the default value) in vPC domain 100:

switch# configuration terminal
switch(config)# vpc domain 100
switch(config-vpc-domain)# reload restore
Warning:
Enables restoring of vPCs in a peer-detached state after reload, will wait for 240 seconds (by default) to determine if peer is un-reachable
switch(config-vpc-domain)#
 

This example shows how to set the delay period for 300 seconds in vPC domain 200:

switch# configuration terminal
switch(config)# vpc domain 200
switch(config-vpc-domain)# reload restore delay 300
Warning:
Enables restoring of vPCs in a peer-detached state after reload, will wait for 240 seconds (by default) to determine if peer is un-reachable
switch(config-vpc-domain)#

Usage Guidelines

By default, the Cisco NX-OS software elects a primary and secondary vPC peer device after you configure the vPC domain and both sides of the vPC peer link. However, you may want to elect a specific vPC peer device as the primary device for the vPC. Then, you would manually configure the role value for the vPC peer device that you want as the primary device to be lower than the other vPC peer device.

A vPC does not support role preemption. If the primary vPC peer device fails, the secondary vPC peer device takes over to become operationally the vPC primary device. However, the original operational roles are not restored if the formerly primary vPC comes up again.

Examples

This example shows how to configure the role priority of a vPC device:

switch(config-vpc-domain)# role priority 100
switch(config-vpc-domain)#
